The buyer, Milano Dolce, is a top-tier Italian premium baking group with over 30 years of expertise in artisanal desserts. Its products are sold in high-end western restaurants and organic boutique supermarkets across Milan and Florence, covering four mid-to-high-end lines: acidic berry jelly, mirror mousse, low-temperature plant-based panna cotta, and ambient coconut soft jelly. All products comply with EU LFGB, Clean Label standards, and KOSHER certification, with an annual agar procurement volume of 38 tons, sourced primarily from imported refined Spanish agar.
Driven by rising overseas raw material prices and delayed ocean freight lead times, the client initiated domestic Chinese agar substitution. After deploying generic domestic food-grade agar in mass production, severe quality defects emerged across all product lines, pushing the finished product rejection rate from the original 3.2% (using imported raw materials) to 21.7% and forcing the delay of new product launches. Although the client’s R&D team was proficient in European formulation systems, they lacked knowledge of domestic agar’s seaweed sources, sulfate content, and gel physicochemical parameters. Multiple adjustments to agar dosage and cooking temperature failed to resolve defects. Recommended by the Sino-Italian Food Ingredients Chamber of Commerce, the client fully entrusted HiSiaddi with fault diagnosis, raw material screening, formula reconstruction, and full-process production line process optimization.
Combining the client’s formulation pH values, cooking procedures, refrigerated storage conditions, and end-product storage environments, HiSiaddi technical engineers decomposed root causes into three categories: improper raw material selection, direct copying of imported formulation parameters, and inadequate production line operation standards.
Generic agar exhibits weak acid resistance; polysaccharide chains hydrolyze and break down in low-pH fruit juice systems, damaging the gel network structure and causing massive juice separation after 7 days of refrigeration, resulting in collapsed products that cannot be demolded. The client blindly increased agar dosage from 0.8% to 1.3%, which yielded overly hard, brittle texture inconsistent with the mild mouthfeel standard for premium desserts. Root Cause: Conventional bulk agar uses mixed algae raw materials with elevated sulfate groups, resulting in poor stability under weak acid conditions.
Generic domestic agar requires prolonged boiling above 98℃ for full dissolution, and extended high-temperature heating depletes natural milk and fruit flavors. Poor powder dispersibility causes agglomeration when directly added to liquid, forming gel particles that appear as white specks on cooled mousse surfaces, failing to meet transparency requirements for premium mirror finishes.
Generic agar has a low melting point (~78℃), insufficient gel stability under high-temperature southern storage conditions, leading to softened edges and water separation in soft jelly that fails to meet the 60-day shelf life standard. The original Spanish imported agar boasts a melting point above 84℃.
Domestic agar features a high gel setting temperature; when following the production rhythm designed for imported agar, liquid mixes rapidly gel after discharge, resulting in uneven mold filling and inconsistent panna cotta size & firmness.
HiSiaddi identified two refined Gracilaria agar manufacturers capable of flexible modified production, rejecting mass-market mixed-algae generic grades, and selected targeted grades aligned with physicochemical requirements of the four product lines:
1. Acid-Resistant Refined Agar (Berry Jelly Exclusive): Manufactured from single-source Hainan Gracilaria with optimized desulfurization processes and low sulfate formula, retaining ≥87% gel integrity in pH 3.5+ systems, perfectly suited for acidic berry formulations.
2. Low-Temperature Instant Ultra-Fine Agar (Mousse Exclusive): Modified 800-mesh powder fully soluble in 70~75℃ warm water without prolonged high-temperature cooking to preserve raw material flavors.
3. High Heat-Resistance High-Strength Agar (Ambient Soft Jelly & Low-Temp Panna Cotta Dual Use): Gel strength of 1100±40g/cm² and melting temperature ≥83℃, balancing high-temperature storage stability and slow gelation rates. 22kg samples of each grade were delivered complete with English COA and third-party LFGB test reports.
1. Acidic Berry Jelly: Reduce agar dosage back to 0.85% and adjust feeding sequence: fully swell and boil agar in neutral pure water first, then cool before adding acidic fruit puree to prevent acid-induced colloid breakdown at high temperatures, eliminating reliance on over-dosing agar to boost hardness.
2. Mirror Mousse: Pre-dry-blend agar with white granulated sugar at a 1:9 ratio before feeding to prevent powder agglomeration, and dissolve at 72℃ low temperature to retain milk aroma.
3. Ambient Coconut Soft Jelly: Fix agar dosage at 0.92% with trace food-grade locust bean gum compounded for synergistic water retention, avoiding melting and delamination under high temperatures.
4. Low-Temperature Plant-Based Panna Cotta: Fine-tune dosage to 0.78% to slow gel formation and match the original filling line production rhythm.
1. Dissolution Process: Segregate cooking temperatures by product line – 72~75℃ for mousse, short-duration boiling at 90℃ for neutral jelly base materials.
2. Feeding Process: Standardize pre-blending dispersion protocols to prohibit direct addition of dry powder into liquid mixes.
3. Filling Process: Raise discharge temperature of panna cotta liquid by 3℃ to extend the workable filling window.
Small-batch pilot production of the three agar grades was verified over five consecutive industrial production days: acidic jelly showed no syneresis or collapse after 60 days of refrigeration, mirror mousse remained transparent and speckle-free, ambient soft jelly retained intact shape for two months under 42℃ storage, and panna cotta achieved uniform filling with consistent texture. Finished product rejection rates dropped to 3.1%, matching the quality of original Spanish imported agar.
The client formally signed an annual 38-ton procurement framework: 15 tons of acid-resistant jelly agar, 12 tons of ultra-fine low-temperature soluble mousse agar, and 11 tons of heat-resistant soft jelly & panna cotta agar, delivered in nine monthly batches. HiSiaddi conducts pre-shipment quality inspection for every batch and compiles full English compliance documentation.
Domestic agar procurement costs fell by 28.3% versus Spanish imports, cutting annual raw material expenditure by 89,000 Euros and recovering over 6,200 Euros in losses from previously scrapped test batches. A new organic tropical fruit gummy line was launched the following year with an additional 6.3 tons of customized agar ordered, establishing a permanent domestic long-term procurement channel.
Leveraging this benchmark high-end European pastry project, standardized process packages for three specialized agar variants (acid-resistant, low-temp soluble, high heat-resistant) were finalized. Customized products command a 34% premium over generic agar, and the client’s endorsement secured sample trial orders from premium baking brands in Switzerland and Greece, escaping domestic low-price raw material competition.
Developed a full technical service model covering agar raw material performance benchmarking → formulation optimization → production line SOP revision → sample follow-up, differentiating us from general traders that only resell off-the-shelf inventory. We subsequently undertook agar technical support and procurement services for mid-to-high-end dessert and dairy enterprises across Western Europe.
Most domestic agar manufacturers focus on mass production of generic mixed-algae agar with broad raw material sources and wide physicochemical parameter tolerances, lacking targeted modification for segmented application scenarios. Formulas developed by European and American high-end baking brands rely on parameter specifications of imported refined agar; direct substitution with generic domestic raw materials inevitably triggers mass production defects including syneresis, agglomeration, and insufficient heat resistance. Drawing on professional colloidal raw material expertise, HiSiaddi implemented comprehensive rectification spanning raw material screening, formula fine-tuning, and production standardization. The solution enabled high-end overseas clients to achieve localized raw material sourcing with stable production and cost reduction, while supporting premium domestic agar manufacturers to access high-value European food ingredient markets, delivering a three-way win-win outcome.
