Please contact HiSiaddi customer service if you require further formulation optimization consulting support.
The buyer, Alpen Feinkost GmbH, is a leading mid-to-high-end local food enterprise based in Vienna, Austria. Its core product portfolio includes low-temperature fermented Western-style hams, restructured raw pork steaks, and whey cheese products, supplied to premium organic supermarkets and fine-dining hotel supply chains across Austria, Germany, and Switzerland. All products comply with EU EC1333, LFGB, and Clean Label regulations. The group historically sourced customized transglutaminase (TG enzymes) from the Netherlands, with an annual total TG enzyme demand of 96 tons (52 tons for ham, 30 tons for restructured meat, 14 tons for cheese). Faced with rising raw material costs and extended delivery lead times for European local enzyme preparations, the client initiated a localization replacement program using Chinese-made raw materials. After generic domestic 100U/g industrial TG enzymes were introduced into mass production, all product lines suffered severe quality defects, pulling the finished product yield rate down from 95.8% (with imported raw materials) to merely 60.3%. Mass batches of finished goods were scrapped, and new product launch plans were suspended indefinitely. The client’s R&D team is proficient in European formulation systems but lacks expertise in the fermentation carriers, activity stability, and acid-base tolerance characteristics of Chinese TG enzymes. Multiple readjustments to enzyme dosage failed to resolve defects. Introduced by the China-Europe Food Ingredients Association, the client entrusted HiSiaddi’s technical foreign trade team to fully oversee fault diagnosis, raw material selection, formulation reconstruction, and full-process production line process optimization.
HiSiaddi engineers disassembled root causes by cross-referencing the client’s raw material formulas, production line temperature control, curing pH values, and maturation processes, categorizing issues into three root causes: improper raw material selection, direct copying of imported formulation parameters, and on-site production operation errors.
The client’s original Dutch TG enzyme was formulated for low-temperature curing at 0–4°C. Generic domestic TG enzymes utilize ordinary maltodextrin compound carriers that delay enzyme activation under cold conditions. When the client retained the imported dosage of 0.28%, meat blocks exhibited weak adhesion after 72 hours of maturation, resulting in cracked, fragmented slices during cutting and excessive finished product loss. Raising the dosage to 0.42% introduced bitter off-notes incompatible with premium fresh meat flavor standards. Root cause: Generic domestic TG enzymes lack low-temperature modification; enzyme protein activity is trapped by carriers under cold conditions, drastically reducing protein cross-linking efficiency.
The ham formulation excludes phosphate water retention agents, with a curing system pH range of 4.9–5.2. Generic TG enzymes demonstrate poor acid resistance, losing over 45% activity after three days of curing. Incomplete myofibrillar protein cross-linking leads to severe water loss during ham air-drying, yielding dry, tough meat that fails to meet the brand’s juicy texture standards. Multiple adjustments to curing temperatures could not offset the enzyme’s inherent acid resistance deficiency.
Cheese is produced from whey and fresh raw milk with a concentration process temperature of 42°C. Generic domestic TG enzymes exhibit weak thermal stability and rapid activity attenuation under heat, resulting in incomplete casein cross-linking. After 15 days of refrigeration, large volumes of whey separate on the cheese surface, causing collapse and deformation, failing to meet the 60-day supermarket shelf-life requirement. Additionally, high impurity levels in generic TG enzyme carriers create fine sediment in cheese, damaging the visual appeal of premium products.
The client retained the European dry feeding process for raw materials. Poor powder flowability of domestic TG enzymes causes agglomeration when directly added to liquid batches, creating localized high enzyme concentrations that trigger excessive partial protein hardening and inconsistent product texture.
HiSiaddi conducted horizontal comparisons across three domestic manufacturers with customized fermentation capabilities, abandoning standard 100U/g generic products and selecting targeted grades matched to each product line:
1. Low-temperature slow-release TG enzyme for restructured meat: Calibrated to 132U/g with modified corn maltodextrin carriers for slow activation under cold conditions at 0–4°C;
2. Acid-resistant TG enzyme for fermented ham: 90U/g, with strain fermentation optimized for stable enzyme activity retention ≥85% across pH 4.8–5.5 to fit low-salt weak-acid curing systems;
3. Heat-resistant TG enzyme for cheese: 98U/g, optimized bacterial protein structure to maintain stable activity under 42°C processing, paired with high-purity low-impurity carriers. 20kg samples of each grade were coordinated for delivery, accompanied by English COA and LFGB test reports.
All meat and dairy raw material ratios remained unchanged, while TG enzyme dosages and auxiliary compound additives were readjusted based on the physical and chemical properties of Chinese TG enzymes:
1. Restructured pork steaks: TG dosage reduced from 0.28% to 0.21%, with 0.05% food-grade dextrose added to assist uniform dispersion, enabling consistent low-temperature cross-linking and eliminating bitterness from excessive enzyme addition;
2. Fermented ham: TG dosage maintained at 0.19%, with trace food-grade sodium citrate compounded as a buffer system to stabilize curing liquid pH and mitigate acid-induced enzyme degradation;
3. Whey cheese: TG added at 0.23%, paired with small amounts of potassium citrate to optimize the casein colloidal environment, boost water retention, and resolve refrigeration whey separation.
HiSiaddi engineers conducted on-site practical rectification at the Austrian factory:
1. Feeding optimization: Pre-blend TG enzyme with white granulated sugar at a 1:5 ratio for dry pre-dispersion, then pre-dissolve in 40°C warm water before adding to the main batching tank to fully eliminate powder agglomeration and fish-eye clumps;
2. Process temperature control: Lower initial ham curing temperature from 8°C to 5°C to slow premature enzyme consumption; stage temperature ramping during cheese concentration to avoid instantaneous high-temperature enzyme deactivation.
Small-batch 500kg pilot production runs were conducted for all three raw materials over four consecutive days of industrial mass production. Restructured meat slices remained intact without fragmentation, ham water loss rates met standards for juicy texture, and cheese maintained shape without whey separation over the full 60-day refrigeration shelf life. The finished product yield recovered to 95.2%, matching quality levels achieved with imported Dutch TG enzymes. The client formally signed a full-year 96-ton framework order: 52 tons for ham production, 30 tons for restructured meat, and 14 tons for cheese, with phased split shipments across 11 batches. HiSiaddi conducts pre-shipment quality inspections for every batch and provides full sets of English compliance documentation.
The comprehensive unit cost of Chinese TG enzymes decreased by 29.2% versus Dutch imports, cutting annual raw material expenditure by 138,000 euros. Losses of 75,000 euros from prior scrapped raw materials and order breach penalties were fully recovered. Supported by optimized formulations, a new plant-based meat line was launched the following year, with an additional 27 tons of TG enzymes ordered for full localization of all product categories.
Backed by this benchmark case for premium Austrian meat and dairy brands, standardized mass production processes were finalized for three specialized TG enzyme variants (low-temperature, acid-resistant, heat-resistant). Customized grades command a 30% premium over generic products, enabling successful business development with comparable premium meat manufacturers in Germany and Switzerland and escape from domestic low-price competition.
A specialized TG enzyme technical service system was established covering imported raw material performance benchmarking, formulation optimization, and on-site production line process guidance, differentiating HiSiaddi from traditional trading companies that only supply off-the-shelf goods. This benchmark case drove continuous development of mid-to-high-end meat and dairy clients across Western Europe.
Most domestic TG enzyme manufacturers prioritize standardized mass-produced generic products, with quality control limited solely to factory exit enzyme activity indicators and minimal investment in application R&D for segmented meat processing scenarios. Formulas developed by European mid-to-high-end meat and dairy enterprises are calibrated around imported customized TG enzyme parameters. Direct substitution with Chinese TG enzymes frequently triggers mass production quality defects due to inherent differences in carrier formulations, temperature/acid resistance, and activation characteristics. Acting as an independent third-party foreign trade partner, HiSiaddi resolves full-chain technical challenges covering raw material selection, formulation adjustment, and production process rectification, delivering cost reduction for overseas clients and high-end overseas market expansion for domestic manufacturers – a three-way win for all stakeholders.
