Dual-Nozzle 3d Printing And Drying Characteristics Of A Hawthorn Snack Based On Dual-Material Combination Gel, Aimiao Wang, Bo Wang, Yuchuan Wang, Jiguang Liu

Journal of Food Science and Biotechnology

[Objective ] This study aims at solving the problems such as long drying time,single product shape,and poor 3D printing capacity (easy blockage and weak bracing ability ) in conventional processing of hawthorn snack products.[Method ] The low-sugar hawthorn jam and high-sugar banana jam were used as gel components.The 3D printing was carried out with the optimization of dual-material combination gel formula and the optimization of dual-nozzle 3D printing process.Furthermore,the drying characteristics of 3D printing were analyzed and compared with those of conventional dried hawthorn products.[Result ] The combination of hawthorn jam with the sugar mass fraction of 26% and banana …

Thawing And Storage Effects On Quality Of Plant-Based Sausage Patties, Dakota Cook

All Theses

Maintaining sausage analogue quality during a thawing process and storage is important for increasing consumer satisfaction. Following new trends and prevalence of plant-based meats and a flexitarian diet, two experiments were conducted to test how thawing methods (experiment 1) and storage temperatures (experiment 2) affect meat analogue quality. For Experiment 1, Jimmy Dean Original Sausage Patties Made with Pork & Turkey, Morningstar Veggie Original Patties and Beyond Sausage Original Patties were purchased pre-frozen and subsequently thawed in one of three ways: 1. thawed at 4°C for 24 hours, 2. thawed at room temperature (22°C±2°C) for 4 hours and 3. thawed …

Postharvest 24-Epibrassinolide And Chitosan Treatments Affect Quality Of ‘Balady Banzahir’ Limes During Shelf Life [Research Note], Mohamed A. Awad, Adel Al-Qurashi

The Philippine Agricultural Scientist

Limes undergo internal metabolic changes during storage at ambient, resulting in rind disorders and green color fading that decrease consumer preferences and market demand. To elucidate the effects of exogenous 24-epibrassinolide (EBR) and chitosan (CT) treatments on the postharvest quality of citrus fruit, freshly harvested mature-green ‘Balady Banzahir’ limes were dipped for 15 min in 20 μM EBR and 1% CT alone or in combination and kept at ambient (23 ± 1°C and 60 – 70% RH) for 20 days. EBR or CT treatments retained fruit quality during shelf life as shown by higher green peel color (lower a* values), …

Evaluating The Effect Of Chitosan, Water-Soluble Chitosan And Chitosan Application Techniques On The Quality Of Refrigerated Catfish Fillets, Franklin Bonilla Torres

LSU Master's Theses

Chitosan (CH) is a biopolymer synthetized by deacetylation of chitin, it is found in the exoskeleton of crustaceans, cell wall of fungi, and insects. CH’s water insolubility limited the used of this compound in some food systems. However, enzymatic hydrolysis of CH yields water-soluble chitosan (WSC). The aim of this study was to evaluate the effect of chitosan, water-soluble chitosan, and chitosan application techniques on the quality of refrigerated catfish fillets. This research was conducted in two separated studies. In the first study, three solution treatments were prepared: (1) a 1% acetic acid (AA) solution, (2) a 0.5% CH solution …

Corn Characterization And Development Of A Convenient Laboratory Scale Alkaline Cooking Process, Shreya N.O. Sahasrabudhe

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Nixtamalized (alkaline cooked) corn (Zea mays L.) products are increasing in popularity due to their affordable cost, ease of production, and the diversity of products that can be made using similar unit operations. The nixtamal produced after alkaline cooking depends on the processing parameters used during cooking and steeping, as well as the physicochemical properties of the corn hybrids used. Processors incur high costs in narrowing down hybrids suitable for a given process, or they must be able to adjust cooking conditions to obtain the desired end-product characteristics. Improper processing generates large quantities of waste. Researchers have developed small …

The Impact Of Delactosed Whey Permeat Treatment On Shelf-Life And Antioxidant Contents Of Strawberries, Catherine Barry-Ryan, Lubna Ahmed, Ana Belen Martin-Diana, Daniel. Rico

Articles

The aim of this study was to investigate the effect of delactosed whey permeate (DWP) 27 treatment on antioxidant and physico-chemical properties of strawberries. Fresh strawberries 28 treated with 3 % DWP were analyzed for different quality, nutritional and microbiological 29 markers during 10 days of storage at 5 °C. The results showed that DWP treatment 30 significantly reduced incidences of decay (70 %) and numbers of total aerobic counts (~1.4 31 Log10 CFU/g) and yeast and moulds (~1.8 Log10 CFU/g). DWP treatment also inhibited the 32 loss of firmness (15 %) and maintained significantly (p

1% Calcium Chloride Treatment In Combination With Gamma Irradiation Improves Microbial And Physicochemical Properties Of Diced Tomatoes, Anuradha Prakash, Pei-Chen Chen, Richard L. Pilling, Nicole Johnson, Denise Foley

Food Science Faculty Articles and Research

The purpose of this study was to determine the effect of a combination of a 1% calcium chloride dip with low dose irradiation on microbial populations, and biochemical and physical properties, of fresh diced tomatoes during a two-week storage period. Vine tomatoes at the light-red stage (trial 1) and Celebrity tomatoes at the table ripe stage (trial 2) were diced, dipped in 1% CaCl2, and irradiated at 1 kGy from a Co-60 source. Tomatoes were also contaminated with cocktail of nalidixic-acid resistant Salmonella strains (S. Poona, S. Hartford, S. Gaminara, S. Michigan, and S. Montevideo) and subjected to gamma irradiation. …

Influence Of Storage Duration, Temperature, And Oxygen On Quality Of Stored Dehydrated Foods, Omima Ali Darag

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was undertaken to determine the effect of oxygen absorber packets (OAP) (AGELESS Z.300 E) in improving the shelf-life of selected dried food products, including dried potato pearls, dried sliced apple, dried carrot, white rice, nonfat dry milk, all purpose flour, rolled oats, and wheat. Items were stored at four different temperatures (-20, 10, 21, and 29.5°C) over a period of 24 months with observations at 6-month intervals. Hunter colorimeter, thiobarbituric acid reactive substance (TBARS) germination rate, gluten weight, and volume were parameters used as quality indicators of various dried foods.

Statistical analysis indicated a significant time and temperature …
